Abstract
An information handling system includes a gesture sensitive interface and a processor. The processor is configured to receive inputs from the gesture sensitive interface corresponding to first and second interaction points, determine a relative motion between the first and second interaction points, and obtain a velocity of the relative motion. The processor is further configured to determine if the velocity exceeds a threshold, and scale an image on a display from an initial magnification to a predetermined magnification when the velocity exceeds a threshold.
Claims16
An information handling system comprising:
- a gesture sensitive interface;
- and
- a processor configured to:
- receive inputs from the gesture sensitive interface corresponding to first and second interaction points;
- determine a relative motion between the first and second interaction points;
- obtain a velocity of the relative motion based on an average velocity of the interaction points;
- determine if the velocity exceeds a threshold;
- determine a scaled magnification necessary to achieve a specified height for the rendered text of a document based on the font size and display size;
- and
- scale an image on a display from an initial magnification to the scaled magnification to achieve the specified height for the rendered text when the velocity exceeds the threshold.
An information handling system comprising:
- a touch sensor;
- a display;
- and
- a processor configured to:
- receive inputs from the touch sensor corresponding to first and second contact points;
- determine a relative motion between the first and second contact points;
- obtain a velocity of the relative motion;
- determine if the velocity exceeds a threshold based on an average velocity of the contact points;
- initiate an audio feedback or a haptic feedback when the velocity exceeds the threshold;
- determine a font size defined for text of a document;
- determine a scaled magnification necessary to achieve a predetermined character height for rendered text of the document based on the font size and the display height;
- and
- scale an image on the display from an initial magnification to the scaled magnification when the velocity exceeds the threshold.
A computer-implemented method comprising:
- receiving inputs from a gesture sensitive interface corresponding to first and second interaction points;
- determining a relative motion between the first and second interaction points;
- obtaining a velocity of the relative motion based on an average velocity of the interaction points;
- determining if the velocity exceeds a threshold;
- determine a scaled magnification sufficient to render characters on a display at a predetermined height, the scaled magnification a function of font size and display height;
- and
- scaling an image on a display from an initial magnification to the scaled magnification when the velocity exceeds the threshold.
